Fading Correction of Readings of Glass Gamma-Radiation Dosimeters SOPD (DTS)-0.05/10 within the Interval of Post-Irradiation Measurements from 1 to 100 Days

This work presents the results of experimental study of post-irradiation variation (fading) of SO PD (DTS) dosimeter readings within the interval from 1 to 100 days after radiation loading by reactor (BR-K1) and bremsstrahlung (LU-10-20) gamma quanta within the interval of absorbed doses from 50 Gy...

Description
Summary:This work presents the results of experimental study of post-irradiation variation (fading) of SO PD (DTS) dosimeter readings within the interval from 1 to 100 days after radiation loading by reactor (BR-K1) and bremsstrahlung (LU-10-20) gamma quanta within the interval of absorbed doses from 50 Gy (water) to 10 kGy (water). There is advanced a formalism for fading correction of dosimeter dose readings based on the application of exponential and logarithmic forms of the functional dependence for the ratios of the light-transmission coefficient conditioned by radiation loading and its values obtained at arbitrary time points after irradiation is completed.
